Hey there Panike,
Hello to you this evening. I would go with a new med and Lexapro seems to work for many. If you do not have an allergic reaction it will take 4-6 weeks for full effect but alot of people like this med.
I tried going back to an old one and it did not work the second time around. Hugs to you and I hope you get this anxiety down to a low roar.
